St. Mary's Church and the Priory, Letheringham, is the nave of a Priory Church founded about 1194. It was the family church of the Wingfields for generations. Unfortunately, the Chancel, where the family monuments were located, was demolished in 1789. Only 2 of the many brasses survive and are mounted on the walls on either side of the altar. (There are also the base stones of several other brasses around the altar that were preserved from the chancel but nothing of the brasses or any other identifier for these stones remain.) Also mounted there are a several memorial plaques that were preserved.
